ABSTRACT:
A power diversion system for a hydraulic dredge diverts any or all available prime mover power to slurry production. An electronic control module (ECM) on the dredge continuously communicates with the prime mover ECM to determine the current available power of the dredge prime mover whether it is an internal combustion engine, electric motor, or other power supply. If the prime mover power supply is not being loaded to capacity the dredge ECM increases the speed of the centrifugal slurry pump to increase production to the point that the least of either the speed that the operator dictates up to 100% of the prime mover power capacity. The system also works in reverse in that if the prime mover is being overloaded, the dredge ECM will automatically reduce pump speed to a predetermined acceptable level.
